WARNING
Closing the sun blind without the roll-back
function can cause serious injuries.
x Always close the sun blind carefully.
x Ensure that nobody obstructs the path
of the sun blind, especially if the roll-
back function is not activ
e when it is
closed.
x The roll-back function does not prevent
fingers or other body parts from being
pressed against the roof frame and sus-
taining injury. Heating and air condi-
tioning system
Heating, v

entilation,
cooling Introduction to the topic
The Climatronic is an automatic air condi-
tioning system that heats, cools and dehu-
midifies the air. Automatic mode enables the
Climatronic to control the air temperature, air
distribution and air v

olume automatically.
The air conditioning system will work most
effectively if the vehicle interior is kept
closed. Opening the windows and glass roof
to provide fresh air may accelerate cooling
down the vehicle if high temperatures have
built up in the vehicle interior.
Display of active functions
Illuminated symbols on the sensor buttons
indicate that the function is switched on.
Colour-coded function buttons display an ac-
tivated function in the climate settings on
the Infotainment system.
Operating the air conditioning system with
voice commands
Depending on the vehicle equipment, some
functions of the air conditioning system can
be operated with the voice control function

Water or water vapour under the vehicle
If the humidity and temperature outside the
v
ehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
If the outside humidity is high and the out-
side temperature low, condensation may
evaporate through the stationary air condi-
tioning when it is running. If this is the case,
steam may appear underneath the vehicle.
This is not a sign that the vehicle is damaged.
Touch panels react differently than expected
Moisture, dirt and grease can impede the
functioning of the touch panels.

fluid. These may leave an oily film on the
window, considerably restricting the field
of vision.
NOTICE
x Ne ver mix suitable cleaning agents with
other cleaning agents. This can cause the
ingredients to separate and block the
washer jets. Coolant
Introduction to the topic
Do not work on the cooling system unless
you are familiar with the task, aware of the
general saf

ety procedures and have the cor-
rect equipment, service fluids and suitable
tools. Failing to carry out work correctly can
cause serious injuries

WARNING
Insufficient anti-freeze in the cooling sys-
tem of the v ehicle can cause the electric
drive to break down and thereby cause se-
rious injuries.
x The amount of correct coolant additive
used must be sufficient for the lowest
ambient temperature that you expect
the vehicle to be exposed to.
x Coolant can freeze at extremely cold
outside temperatures, causing the vehi-
cle to break down. Vehicle occupants
with inadequate winter clothing could
then freeze to death as the heating will
also no longer function. NOTICE
Never mix genuine coolant additives with
other coolants that ha
ve not been approved
by Volkswagen.
x If the liquid in the coolant expansion tank
is not pink (colouring results from mixing
the purple coolant additive with distilled
water) but for example brown instead of
purple, the suitable coolant has been
mixed with an unsuitable coolant additive.
The coolant must be changed as soon as
possible if this is the case. Failure to ob-
serve this warning can result in serious
malfunctions or damage to the electric
drive and cooling system. Coolant and coolant additives can pol-
lute the en

vironment. Spilt service flu-
ids must be collected and disposed of proper-
ly and with respect for the environment. Checking the coolant level
and refilling coolant

2. Allow the electric drive to cool down

cooling system when the engine is hot and
could cause damage.
x If a large amount of coolant has been lost,
do not refill the coolant until the engine
has cooled completely. Hea
vy coolant loss
is an indication of leaks in the cooling sys-
tem. The cooling system should be
checked by a qualified workshop as soon
as possible. Failure to do so can result in
engine damage.
x Do not refill coolant if there is no more
coolant in the coolant expansion tank. Air
could have entered the cooling system. Do
not drive on! Seek expert assistance. Fail-
ure to do so can result in engine damage.
x When refilling service fluids, please ensure
that you pour the correct service fluids in-
to the correct openings. The use of incor-
rect service fluids can result in serious
malfunctions and damage to the electric
drive. Troubleshooting
Please refer to , and on page 309
and at the start of the chapter on page
315. Coolant

Stop the vehicle as soon as possible and
when safe to do so.
